You've made a couple of interesting decisions (that I may not have done if I were writing this myself): * Picking CSC over Visual Studio for compiling initially * Explaining namespaces thoroughly in part 2, then glossing over them in 3 (I also don't know if I entirely agree with what's under "Using Statement") No major criticisms with structure/style/order. I find that when teaching a programming language you just wind up dumping information on the person learning until a point where everything clicks, so the order of explaining this stuff probably isn't that important. One thing that I'd suggest fixing is the indentation on the code. The number of spaces being inconsistent is something that could massively throw off people who don't understand nesting. Other than this, it's a good set of tutorials so far IMO.
